| Abstract | The biological activity and optimum conditions for threeleaf cayratia(Cayratia trifolia L.) wine fermentation using Saccharomyces cerevisiae HG1.3 were studied. The tests on the effect of fermentation conditions, including initial total sugar content (20, 22, 24 ?Brix), pH (4.0, 4.5, 5.0), inoculum concentration (103, 105, 107cells/mL), and temperature (30, 35, 37, 39, 41 ?C) indicated that the ethanol contents of threeleaf cayratiawine were 5.1912.82% (v/v). The results showed that appropriate fermentation conditions were 35 ?C, 20 ?Brix, 105cells/mL yeast cells, and 6 days. The ethanol content of the final product was 11.68% (v/v) and the methanol, SO2, hydrocyanic acid, and aldehyde concentrations were acceptable according to Vietnam National Standard 7045:2002. The total polyphenol content and antioxidant activity of threeleaf cayratiajuice (0.66 mg gallic acid equivalents (GAE)/mL and 54.7%, respectively) and wine (0.60 mg GAE/mL and 57.4%, respectively) were not significantly different. |
